+    The only difference to the original class created by Javac or Ajc is that the bridge method is written to the class
+    file first, then the overriding method with the return type narrowed from Iterable to List. This has the effect of
+    org.aspectj.weaver.ResolvedType.getMethodsIncludingIntertypeDeclarations also finding the bridge method first,
+    which helps to reproduce https://github.com/spring-projects/spring-framework/issues/27761 in a regression test.
+
+    The resulting class file can be found in .../gh_spring_27761/JpaRepository_bridge_first.jar and is used during test
+    "do not match bridge methods".
